Clusters API

The clusters API endpoint lets you create and manage clusters in your organization.

Clusters

A cluster is an isolated set of agents and pipelines within an organization.

Cluster data model

`id`	ID of the cluster
`graphql_id`	GraphQL ID of the cluster
`default_queue_id`	ID of the cluster's default queue. Agents that connect to the cluster without specifying a queue will accept jobs from this queue.
`name`	Name of the cluster
`description`	Description of the cluster
`emoji`	Emoji for the cluster using the emoji syntax
`color`	Color hex code for the cluster
`url`	Canonical API URL of the cluster
`web_url`	URL of the cluster on Buildkite
`queues_url`	API URL of the cluster's queues
`default_queue_url`	API URL of the cluster's default queue
`created_at`	When the cluster was created
`created_by`	User who created the cluster

List clusters

Returns a paginated list of an organization's clusters.

Example: "The default queue for this cluster"

hostedAgents Configures this queue to use Buildkite hosted agents, along with its instance shape. This makes the queue a Buildkite hosted queue.
Example:
{ "instanceShape": "LINUX_AMD64_2X4" }
instanceShape (required when hostedAgents is specified): Describes the machine type, architecture, CPU, and RAM to provision for Buildkite hosted agent instances running jobs in this queue.
It is only possible to change the size of the current instance shape assigned to this queue. It is not possible to change the current instance shape's machine type (from macOS to Linux, or vice versa), or for a Linux machine, its architecture (from AMD64 to ARM64, or vice versa).
Learn more about the instance shapes available for Linux and Mac Buildkite hosted agents.

Agent tokens

An agent token is used to connect agents to a cluster.

Token data model

`id`	ID of the token
`graphql_id`	GraphQL ID of the token
`description`	Description of the token
`allowed_ip_addresses`	A list of CIDR-notation IPv4 addresses from which agents can use this token
`url`	Canonical API URL of the token
`cluster_url`	API URL of the cluster the token belongs to
`created_at`	When the token was created
`created_by`	User who created the token

List tokens

Returns a paginated list of a cluster's agent tokens.
